Is there any open source library available meant for image filtering effects(like fisheye, old movie etc.), based on opencv library. If you refer to any book/site on opencv which will be helpful for this purpose, I will be extremely grateful.

There isn't any based on OpenCV, because this is not the purpose of OpenCV. On the other hand, a very popular library for this is ImageMagick.

ImageMagick comprises a set of tools to to create, edit, compose, or convert images, but it also provides a C++ API through Magick++, which is what you should take a look at.

I also suggest you check Fred's ImageMagick Scripts for a list of several effects that were easily achieved using ImageMagick tools.

  • Thanks, Imagemagick will be much useful at least in this case. The reason I want to use opencv is that, my application have also face detection feature. Lot of example already available in opencv regarding this. I can use both, but it will be great if I achieve all effects easily using opencv alone. – biztiger Jan 21 '12 at 17:12
  • OpenCV was not designed for image effects and a lot is missing to achieve this task easily. I believe a mix of OpenCV-ImageMagick is what you should use to do the job. – karlphillip Jan 21 '12 at 18:23

Read Gary Bradsky's "Learning OpenCV". It has details about fisheye distortion. Or checkout this SO, which also deals with fisheye effect and its simulation. Old picture effect is explained in this SO.
